The invention discloses a special crane for loading and unloading ton bags, and relates to the technical field of cranes. The trolley moves on the upper side of the bridge frame based on the running mechanism, and a rigid guide column is mounted on the lower side of the trolley; a rolling wheel is installed on the upper side of the rotary lifting appliance, the rolling wheel is connected with the output end of the trolley based on a steel cable, and the rolling wheel drives the rotary lifting appliance to ascend or descend along the rigid guide column; and at least one group of self-locking mechanism is arranged on the lower side of the rotary lifting appliance and is used for automatically unhooking the ton bag. The crane is designed based on the ton bags, the horizontal direction of the rotating lifting appliance in the crane can be adjusted, and the self-locking mechanism is matched, so that the ton bags can be conveniently loaded and unloaded; and when the ton bag is lifted, the moving stability can be improved through the rigid guide columns.

    本发明公开了一种吨袋装卸专用起重机,涉及起重机技术领域,包括桥架,内部安装有运行机构;小车,基于运行机构在桥架上侧进行移动,且小车的下侧安装有钢性导柱;旋转吊具,上侧安装有卷轮,所述卷轮基于钢索与小车的输出端相连接,且卷轮带动旋转吊具沿钢性导柱进行上升或下降;自锁机构,至少一组安装在旋转吊具的下侧,对吨袋进行自动脱钩。本申请中的起重机基于吨袋进行设计,其内部旋转吊具的水平方向可进行调节,并且配合自锁机构,可以方便对吨袋进行装卸;并且在提升吨袋时,通过钢性导柱,可以提高移动时的稳定性。
